COSTA, Roberto Germano et al. Meat quality of lambs fed silk flower hay (Calotropis procera SW) in the diet. R. Bras. Zootec. [online]. 2011, vol.40, n.6, pp.1266-1271. ISSN 1806-9290.

The objective of this work was to evaluate the influence of using silk flower hay replacing corn and soybean meal on physical-chemical and sensorial traits of lamb meat. It was used 32 intact Morada Nova male lambs (12.7 ± 2 kg initial body weigth) on feedlot system, distributed in a completely randomized design with four levels (0, 15, 30 and 45% on dry matter basis). The use of silk flower hay in the diet influenced quality of meat and carcass, leg weight, tissue composition, moisture, juiciness and flavor. Replacing corn (26.67%) and soybean (3.33%) with silk flower hay does not affect the tissue composition, ratios and muscularity index of leg and physical-chemical parameters of semimembranosus muscle of Morada Nova lambs.

Keywords : carcass; flavor; Morada Nova; muscularity; native breed.
